Why choose surveillance? 

Surveillance is often used to obtain vital evidence, locate assets, identify people and to covertly observe activities of an individual or group. Surveillance is a tool that is also used for intelligence gathering in a legal matter. Surveillance can be on foot, mobile in a motor vehicle or a more covert (undercover) method. The type and location of assignments often dictates the most appropriate method of surveillance by a private investigator.
